This was cute and fun! I got frustrated during my first playthrough because I didn't realize that ingredient order was important. After that, I started to get the hang of it.
I was playing the original upload, not the postgame patch, which I assume is why I didn't seem to get any keys. I delivered about 8 to 10 recipes and the exit door didn't seem to change, so I just quit. Despite that, I still had fun :)
